Definitions
- the present disclosure relates to a drive system of an electric vehicle. More particularly, it relates to a drive system of an electric vehicle which includes a motor, a reducer, and an axle for driving the electric vehicle.
- the pure electric vehicle is a battery electric vehicle in which a battery alone is mounted as a high voltage power supply and a motor is driven using electrical energy charged in the battery.
- the fuel cell vehicle is a vehicle in which both a fuel cell using hydrogen fuel and a battery are mounted as high voltage power supplies and a motor is driven using power generated by the fuel cell and power charged in the battery.
- the hybrid electric vehicle is a vehicle which is driven using both a motor and an engine as hybrid drive sources.
- the fuel cell vehicle and the hybrid electric vehicle are also driven by power of the motor by driving the motor using electrical energy and may thus be referred to as electric vehicles in a broad sense.
- a hydrogen electric truck or a hydrogen electric bus in which a fuel cell, which is a kind of power generation apparatus, is mounted has been actively developed as a solution to overcome a battery capacity problem in large vehicles, such as trucks, buses, and the like.
- FIG. 1 is a view illustrating a drive system of a hydrogen electric truck, in which the following are arranged: a fuel cell 1 serving as a main power source (an electric power source); a motor 2 serving as a drive device to drive the vehicle; a transmission (or a reducer) 3 to change the rotational speed of the motor 2 ; a propeller shaft 4 to transmit rotating power output from the transmission 3 ; and a rear axle 5 to transmit the rotating power transmitted through the propeller shaft 4 to vehicle wheels.
- a fuel cell 1 serving as a main power source (an electric power source)
- a motor 2 serving as a drive device to drive the vehicle
- a transmission (or a reducer) 3 to change the rotational speed of the motor 2
- a propeller shaft 4 to transmit rotating power output from the transmission 3
- a rear axle 5 to transmit the rotating power transmitted through the propeller shaft 4 to vehicle wheels.
- This arrangement of the drive system is the same as one applied to a truck in which a diesel engine is mounted.
- the electric truck uses the arrangement of the drive system, similar to that of the diesel truck, including the motor 2 , the transmission 3 , and the rear axle 5 .
- the configuration of the drive system applied to the diesel truck is applied to the hydrogen electric truck, parts for diesel engines may be applied thereto.
- the configuration of the system may be simple and a part development period may be shortened.
- the drive system including the motor 2 , the transmission 3 , and the rear axle 5 occupies the entire space inside vehicle body frames.
- a battery, a controller, high-voltage electric parts, a hydrogen tank, and the like must be arranged outside the vehicle body frames.
- a drive system having an improved arrangement in which an available space inside vehicle body frames may be ensured so that a battery, high-voltage electric parts, a hydrogen tank, and the like may be arranged inside the vehicle body frames is required.
- the present disclosure has been made in an effort to solve the above-described problems associated with the prior art. It is an object of the present disclosure to provide a drive system of an electric vehicle having an arrangement optimized for characteristics of a hydrogen electric truck so as to ensure an available space inside vehicle body frames.
- the vehicle body may allow a battery, high-voltage electric parts, a hydrogen tank, and the like to be arranged inside the vehicle body frames and to increase space utilization in the vehicle.
- the present disclosure provides a drive system of an electric vehicle.
- the drive system includes a motor configured to drive the electric vehicle, one of a reducer or a transmission connected to an output side of the motor so as to change a rotational speed of the motor, and a rear axle configured to transmit rotating power output from the reducer or the transmission to vehicle wheels.
- the motor and the reducer or the transmission together with the rear axle are mounted on a suspension.
- an output side of the one of the reducer or the transmission may be directly connected to the rear axle so as to form an integral structure in which the motor, the reducer or the transmission, and the rear axle are directly connected.
- the rear axle, the one of the reducer or the transmission, and the motor may be sequentially arranged in forward and backward directions of a vehicle body.
- the one of the reducer or the transmission and the motor may be arranged at the rear of the rear axle in forward and backward directions of a vehicle body.
- the motor, the one of the reducer or the transmission, and the rear axle may be arranged in an inner space between left and right vehicle body frames arranged in forward and backward directions of a vehicle body.
- the motor, the one of the reducer or the transmission, and the rear axle may be located under the left and right vehicle body frames so as not to protrude upwards from upper ends of the left and right vehicle body frames.
- the electric vehicle may be a hydrogen electric truck provided with a fuel cell mounted therein, and a space to accommodate a battery or a hydrogen tank arranged therein may be prepared in front of the rear axle within the inner space between the left and right vehicle body frames.
- the drive system may further include a mounting structure configured to mount and support the motor on left and right lower arms of the suspension and configured to support air springs arranged between the suspension and vehicle body frames.
- the mounting structure may include a sub-frame installed to connect the left and right lower arms of the suspension and insulators interposed between the sub-frame and the motor.
- the sub-frame may be located under the motor and support the motor in a state in which the insulators are interposed between an upper surface of the sub-frame and a lower surface of the motor.
- coupling positions between the lower arms and the sub-frame may be set to be located directly under the air springs of the suspension supported by upper portions of the lower arms, such that the sub-frame may be located directly under the air springs.
- a middle portion of the sub-frame may have a downwardly bent shape corresponding to a lower surface of the motor having a cylindrical shape.
- the insulators may be interposed between left and right sides of the lower surface of the motor and left and right sides of an upper surface of the sub-frames corresponding thereto.
- each of the insulators may include a first plate coupled to the sub-frame, a second plate coupled to the motor, and an elastic member interposed between the first plate and the second plate.
- motor brackets may be installed on an outer surface of the motor and the second plate of each of the respective insulators may be coupled to each of the respective motor brackets.
- the electric vehicle may be an electric truck and the electric vehicle may be a hydrogen electric truck provided with a fuel cell mounted therein.

- the module including the drive system 30 (i.e., the E-axle) and the suspension 20 may be separated downwards from the vehicle body frames 10 so as to be repaired.
- a hydrogen electric truck may be operated with maintainability and assembly performance which are on the same level as those of the conventional diesel truck.
- the drive system 30 according to the present disclosure is advantageous not only in terms of inline investment costs and equipment costs but also in terms of equipment response of vehicle operation enterprises and maintenance enterprises.
